These all new multiconductor feedthroughs are designed for use in applications that require several sensors to pass through a wall or bulkhead at one opening or within a small area. Heavy duty 416 stainless steel construction allows this fitting to be used in high pressure or vacuum applications. Probes between 0.40" and 1/4" in diameter can be used in these feedthroughs. The maximum number of probes per feedthrough is 3 for 1/4" diameter probes, 5 for 3/16" diameter, 8 for 1/8" diameter, 16 for 1/16" diameter, and 16 for 0.40" diameter probes.
FEATURES
3 to 16 Probes
416SS Body and Cap
316SS Ferrules Standard
PTFE Ferrules Available
Uses Standard OMEGALOK® Ferrules
.040 Through 1/4" Diameter Probes
Blank Sealing Plugs Included at No Extra Charge

All multiconductor feedthroughs are supplied in standard form with stainless steel ferrules. A stainless steel ferrule deforms and becomes permanent. If it is required that the probes be installed several times at different depths in the feedthrough, PTFE ferrules should be used. PTFE ferrules will not deform the probe sheath, allowing the same probe to be reused. The ferrules used in the feedthroughs are identical to the ferrules used in standard OMEGALOK® compression fittings.
PTFE Tape
 13 mm x 6.6 m (1/2 x 260")

PTFE tape should be used on all pipe joints to provide a good seal and to prevent the threaded parts from seizing each other on disassembly.

For probes and/or OMEGACLAD® metal-sheath cable,See section A(Thermocouples) and C (RTD’s)for probes and Section H for wire and cable. Contact sales for custom assemblies.
